Clojure supports functions with multiple arities (http://clojure.org/ functional_programming).
Assuming you don't actually care if you call the function with a vector, you can do something like this: (defn sum ([] 0) ([acc & r] (if (nil? r) acc (recur (+ acc (first r)) (rest r))))) Not sure if that is precisely what you want or not.
